monthly salary of a teacher was Rs 12000 last month.lf the salary increase by 20% find his salary this month
Answer:
new salary = ₹ 14400
Step-by-step explanation:
here's your solution
==> monthly salary = ₹ 12000
==> percentage increase in salary = 20%
=> we need to find 20% of 12000
==> increased amount = ₹ 2400
==> salary of this month = 12000 + 2400
==> new salary = ₹ 14400

A car's velocity, in mph, is recorded simultaneously by five different sensors, with the results: 45, 46, 46, 45, 48. Estimate a range of values in which the car's true velocity is likely to lie.
Answer: [tex]45-48\ \text{mph}[/tex]
Step-by-step explanation:
Given
Car velocity is given by [tex]45, 46, 46, 45, 48[/tex]
The range of a given set of data is given by
[tex]\text{Range=Max-min. value}[/tex]
Maximum velocity=48
Minimum velocity=45
The Range of velocity is
[tex]\Rightarrow 48-45=3[/tex]
Velocity lies between [tex]45-48\ \text{mph}[/tex]

(45 is incorrect I know that already)
Answer:
∠ B = 60°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(10x - 45)° is an exterior angle of the triangle , then
10x - 45 = 3x + 4x = 7x ( subtract 7x from both sides )
3x - 45 = 0 ( add 45 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
Then
∠ B = 4x = 4 × 15 = 60°
Answer:
∡B=60°
Step-by-step explanation:
x = 15
so 4x = 60
7x + 180 - (10x-45) = 180
-3x + 225 = 180
-3x = -45
x = 15
Find the volume of the sphere. Round your answer to the nearest tenth.
Answer:
See below.
Step-by-step explanation:
The formula for the volume of a sphere
= 4/3 π r^3 where r = the radius.
So for number 1:
V = 4/3 π (5)^3
= 523 .60 mm^3 to nearest hundredth.
The others are solved in exactly the same way except where the diameter is given as in number 4 and 5 you get the radius r by dividing the diameter by 2. So in number 4, r = 30/2 = 15.

Graph a line that is perpendicular to the given line. Determine the slope of the given
line and the one you graphed in simplest form. Click and drag on the graph to draw a
line.
Answer:
Original slope: 3/4
Perpendicular slope: 4/3
Step-by-step explanation:
Find the original slope by using rise over run, then flip the original slope which finds your perpendicular slope.
Find the area of this parallelogram. Be sure to include the correct unit in your answer.
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
Answer:
A = 126 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 14 and h = 9 , then
A = 14 × 9 = 126 cm²
A square garden has sides that are 17 meters long. Fencing costs $9.00 per meter. How much would it
cost to put a fence around the garden?
Answer:
$612
Step-by-step explanation:
Each side of the square garden is 17 meters, and fencing costs $9 per meter. "Around" is the key word, as it indicates perimeter. So, we just need to account for each side of the garden, and not the entirety of the garden. So,
17 · 9 = 153
This means that to cover one side of the garden, it would cost $153. Now, we just need to account for all sides of the garden.
153 x 4 = 612
Answer:
The answer would be 612$ to put a fence around the garden
or 153 for 17 meters
Step-by-step explanation:
I believe that it is 612 because it says sides

The ages in years of eight boys are 14,
14.5, 12, 11.5, 15, 13, 10.5, 13.5. What is
their average age?
A. 14 B. 13
C. 12 D. 11
Answer:
B) 13
Step-by-step explanation:
Average age means to calculate mean:
Mean = (Sum of all numbers)/(Number of numbers)
Mean = (14 + 14.5 + 12 + 11.5 + 15 + 13 + 10.5 + 13.5)/8
Mean = (104)/8
Mean = 13

solve 6x + 6 = 3x - 6
Answer:
x = -4
I hope it's helps you t
Answer:
x = -4
Step-by-step explanation:
Simplifying
6x + 6 = 3x + -6
Reorder the terms:
6 + 6x = 3x + -6
Reorder the terms:
6 + 6x = -6 + 3x
Solving
6 + 6x = -6 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
6 + 6x + -3x = -6 + 3x + -3x
Combine like terms: 6x + -3x = 3x
6 + 3x = -6 + 3x + -3x
Combine like terms: 3x + -3x = 0
6 + 3x = -6 + 0
6 + 3x = -6
Add '-6' to each side of the equation.
6 + -6 + 3x = -6 + -6
Combine like terms: 6 + -6 = 0
0 + 3x = -6 + -6
3x = -6 + -6
Combine like terms: -6 + -6 = -12
3x = -12
Divide each side by '3'.
x = -4

A triangle has sides with lengths of 26 inches, 73 inches, and 76 inches. Is it a right triangle?
Answer:
No, it is not a right triangle.
Step-by-step explanation:
We know that there are 2 legs and 1 hypotenuse. The hypotenuse is 76 because it is the largest number. And the two legs are 73 and 26. Now to find if it is a right triangle we will take 73 and multiply it by itself, which is 5,329. Now we will do the same with 26 and we get 676. Then we add 676 to 5,329 and we get 6,005. Because we are trying to find the hypotenuse, we have to find what number when squared makes 6,005. Since 76 x 76 = 5,776 it is not a right triangle.
Here is an image of the triangle:

A basketball stadium has 15 ,002 zero seats the lower level has 54 than three times as many seats as the upper level the middle level has 40 more than twice as many seats as the upper level used to solve for x and found that the upper level has 2,502 sears
Answer:
There are 7456 seats on the lower level and there are 5044 seats on the middle level.
Step-by-step explanation:
Let 'X" be the number of seats on the upper level. Then we can find how many seats are on the lower level by solving the following equation...
# of seats on the lower level = 3x - 50
# of seats on the lower level = 3(2502) - 50
# of seats on the lower level = 7456
Now we just make the equation for the number of seats on the middle level, and so we get...
# of seats on the middle level = 2x + 40
# of seats on the middle level = 2(2502) + 40
# of seats on the middle level = 5044
